1. A method comprising:
- receiving a depth map for a multi-view frame, the multi-view frame comprises a multi-view coding block and the multi-view coding block comprises a 2D coding block;
computing a depth quality sensitivity measure for the multi-view coding block in the multi-view frame based in part on the received depth map;
computing a depth-based perceptual quantization scale for the multi-view coding block, wherein the depth-based perceptual quantization scale is based on the depth quality sensitive measure and a base quantization scale for the multi-view frame; and
encoding the 2D coding block using the depth-based perceptual quantization scale.

Abstract
A method for encoding a multi-view frame in a video encoder is provided that includes computing a depth quality sensitivity measure for a multi-view coding block in the multi-view frame, computing a depth-based perceptual quantization scale for a 2D coding block of the multi-view coding block, wherein the depth-based perceptual quantization scale is based on the depth quality sensitive measure and a base quantization scale for the 2D frame including the 2D coding block, and encoding the 2D coding block using the depth-based perceptual quantization scale.
